We present a derivation of Wandzura-Wilczek (WW) like relations for skewed par-ton distributions. It is demonstrated for photon-pion scattering that the skewed twist-3 parton distributions contributing to the DVCS amplitude have discontinuities at the points x = ±ξ in the WW approximation. This may lead to a violation of factorisation for the twist-3 DVCS amplitude with transverse polarization ...

In this rejoinder I respond separately to Daniel Fishman’s and Ronald B. Miller’s respective arguments regarding my views about objectivity and causality, owing to the fact that Fishman finds a place for “objectivity” and “causality” within his theoretical model whereas Miller does not. First, I question the basis for Fishman’s conclusion that coherence and pragmatic models are objectivist acco...

This paper presents an overview of the main issues associated with the economics of offshore wind. Investment in offshore wind systems has been growing rapidly throughout Europe, and the technology will be essential in meeting EU targets for renewable energy in 2020. Offshore wind suffers from high installation and connection costs, however, making government support essential. We review variou...

We present a multiperiod agency model of stock based executive compensation in a speculative stock market, where investors have heterogeneous beliefs and stock prices may deviate from underlying fundamentals and include a speculative option component. This component arises from the option to sell the stock in the future to potentially overoptimistic investors. We show that optimal compensation ...

Offshore wind is the logical next step in the development of wind energy. With higher wind speeds offshore and the fact that turbines can be placed out of sight, offshore wind helps increase the amount of renewable energy signifi cantly. Offshore wind has been developed through pilot projects in the 1990s and has seen commercial development over the last decade. This chapter shows the developme...

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract In this article we will show that the Total Ozone Residuals (TOR) method as presented by Fishman et al. (2003) contains an erroneous assumption, due to which the TOR as presented in this article reflects mainly a tropospheric O 3 climatology (Logan, 1999)...

We prove that the countable intersection of C1-diffeomorphic images of certain Diophantine sets has full Hausdorff dimension. For example, we show this for the set of badly approximable vectors in Rd, improving earlier results of Schmidt and Dani. To prove this, inspired by ideas of McMullen, we define a new variant of Schmidt’s (α, β)-game and show that our sets are hyperplane absolute winning...

We have explored educational methods for algorithmic thinking for novices and implemented a block programming editor and a simple learning management system. In this paper, we propose a program/algorithm complexity metric specified for novice learners. This metric is based on the variable usage in arithmetic and relational formulas in learner’s algorithms. To evaluate the applicability of this ...

Theoretically expected natures of a supernova driven by a wind/jet are discussed. Approximate analytical formulations are derived to clarify basic physical processes involved in the wind/jet-driven explosions, and it is shown that the explosion properties are characterized by the energy injection rate (Ėiso) and the mass injection rate (Ṁiso). To explain observations of SN 1998bw associated wit...
